HYDROCARBON-VAPORIZER.

SPECIFICATION forming part of Letters Patent No. 400,313, dated March26, 1889.

(No model.)

To to whom it may concern.-

Be it known that I, HENRY C. DAVIS, a citizen of the United States,residing at Terre Haute, in the county of Vigo and State of Indiana,have invented a new and useful Improvement in Hydrocarbon -Vaporizers,of which the following is a specification.

My invention relates to a hydrocarbonburner having certain novelfeatures of c011- struction and arrangement, to be hereinafter pointedout, and which is particularly adapted for use in connection witha'stove.

The accompanying drawings illustrate my invention.

Figure 1 represents a view in perspective of the generator and burner.Fig. 2 repre sents a transverse section of the same, on a smaller scale,arranged for use in the fire-pot of a stove.

A and B represent a pair of retorts, formed preferably of wrought-irontubes, having their ends closed by heads welded therein. retorts areprovided with supply-pipes c and d, which lead, respectively, to thewater-tankl and the oil-tank m, and theirinteriors are connected at oneend by the pipe 6. Above the 'retorts A and B is a cylindricalreservoir, F,

which is also formed,preferably, of wroughtiron tube having theendsclosed by welding a head therein. Theinterior of reservoir F isconnected with the interior of retort B, opposite to that end of saidretort which is con- From the other end of reservoir F a pipe, 1',passes downward and then horizontally underneath, between, and parallelwith the retorts A and B. The lower or horizontal portion of pipe 45 isprovided on its upper surface with a series of narrow longitudinalslots, j, and its extreme end is closed. Arranged between and slightlyabove the retorts A and B is a sheet of metal, forming a deflector, 70.

It will be understood that, the retorts having been first heated by'afire built beneath them, water is admitted to retort A and oil toretortB through the supply-pipes c and (Z. The water, being vaporizedand the vapor be ing superheated in retort A, passes through the pipe 6to the retort B, where it unites with the vapor of the oil, and the gasthus formed passes through pipe h to the reservoir F, where it is stillfurther heated, and, issuing Said thence through the pipe 2', isdischarged and burned at the slots j, thus making the processcontinuous.

It is found necessary to the attainment of the best results in thisclass of vaporizer that the proportions of water and oil admitted to therespective retorts be uniform. For the purpose of effecting this result,having previously determined the proper relative proportions of waterand oil, I arrange the valves '17, and o in the supply-pipes c and d, sothat their stems may be connected by a pair of gears, 19 and r, havingthe same relative proportions, so that upon either valve-stem beingturned to open the valve the other Valve is also turned so as to admitthe proper pro portionate amount. It has also been found that in thisclass of vaporizer the sudden admission of cold air to the stove inwhich they were arranged has so lowered the temperature of the gas as tocause it to smoke badly in burning. For the purpose of avoiding thisdifficulty, and also to avoid the loud noise of the escaping gascommonly found in these burners, I arrange the vaporizer in the firepotof a stove, as shown in Fig. 2.

T represents the grate in the bottom of the fire-pot U. The vaporizerrests on this grate and is surrounded by a sheet-iron casing, 12,(indicated also in dotted lines, Fig. 1,) which is open at the top andbottom, the lower end of the casing resting on the grate, and therebeing an opening, t, in the side, through which kindlings may be laid onthe grate beneath the generator. The space above and around thegenerator, between it and the casing o, is now filled with irregularbits of slag, w, firebrick, or other like incombustible and refractorymaterial, the object being to prevent the too rapid escape of the gas,to distribute the flame over a large surface, and to retain the heatabout the retorts, the receiver, and their connections. By this meansall parts of the generator are kept at a uniform and high temperatureand a perfect and nearly noiseless combustion of the gas is secured.-

The casing *0, when burned out, may be easily removed and cheaplyreplaced, thus saving the sides of the stove.

I claim as my invention 1. The combination, with a stove having a grate,of a hydrocarbon-burner, a vaporizingretort, a steam-generating retort,and a mixing-chamber, all situated within the fire-pot of the stove, aremovable metal casing surrounding the said parts and resting on thegrate, and having an opening, I, in its side adjacent to the grate,whereby heat from burning material upon the grate will pass through thesaid opening and heat the said parts when it is Wished to start theburner, and a mass of refractory material Within said casing,substantially as described.

2. In a hydrocarbon-burner, the combination of the Water and oil retortsA and 13, lying side by side, the burner situated below the HENRY C.DAVIS.
